Subject: [PATCH] net/ipv6: Fix a test against 'ipv6_find_idev()' return value
Date: Fri, 28 Dec 2018 23:28:21 +0100 [thread overview]
Message-ID: <20181228222821.20332-1-christophe.jaillet@wanadoo.fr> (raw)
'ipv6_find_idev()' returns NULL on error, not an error pointer.
Update the test accordingly and return -ENOBUFS, as already done in
'addrconf_add_dev()', if NULL is returned.
Fixes: ("ipv6: allow userspace to add IFA_F_OPTIMISTIC addresses")
